Inductive sensing provides contactless sensing of conductive objects using only an AC magnetic field. Inductive sensing (LDC) devices use the change in resonant frequency of an inductive-capacitive (LC) tank to detect the change in inductance of a given sensor. Nearby conductive targets interact with the magnetic field of the LC sensor, causing eddy currents to form on the surface of the conductor. This causes a change in the characteristics of the resonant sensor which the LDC digitizes.
